thank you very much!

hi to all can I change num-replicas on pool online? I need to change it from 2 to 3 and min_size from 1 to 2 can i do it on the fly? and if yes, than how? from gui (how?), or from console by command ceph osd pool set data size 3 ceph osd pool set data min_size 2 thanks!

after unclean shutdown my ceph cluster has some errors, and some of this errors can't be fixed by "ceph pg repair" thats what i seen in log: cluster [ERR] deep-scrub 1.774 24ac1774/rbd_data.511d802ae8944a.0000000000006285/head//1 on disk size (4194304) does not match object info size (2113536)...

What should i do? what service i need to restart to fix this situation? what logs should i watch?

we used shared nfs storage with connection to vmware and to proxmox, we moved our vm`s to nfs, than convert their to raw, attach converted disk to created vm on proxmox, then moved disk from nfs to rbd with proxmox... profit
